Application filed January 5, v19%1. Serial No. 435,183.

To all whom it may concern:

Be it known that we, BURT C. ALvoRD and CHARLES A. Gunmen, citizens ofthe United States, residing at Le Grand, county of h lerced, State ofCalifornimhave in-" This invention relates to improvements in devicesfor injecting water or steam with the ingoing charge for an internalcombustion engine. 1

Some provision however should be made to insure that the supply of steamor water is proportional to the amount of fuel drawn into the engine,and to successfully accomplish this in an automatic manner forms theprincipal. object of our invention.

Another object is to provide a device for the purpose which may be usedin connection with almost any make of carbureter, and is operated andcontrolled by the moving of the throttle or butterfly valve of thecarbureter.

A further object of the invention is to produce a simple and inexpensivedevice and yet one which will be exceedingly effective tor the purposeswhich it is designed.

These objects we accomplish by means of such structure and relativearrangement of parts as will fully appear by a perusal of the followingspecification and claim.

In the drawings similar characters of reference indicatecorrespondingparts in the several views.

Fig. 1 is a top plan view of the device, showing the same installed inconnection with a certain form of carbureter.

Fig. 2 is a sectional elevation of the device, showing the method ofautomatically controlling the flow of water by the throttle of thecarbureter.

Fig, 3 is a fragmentary cross section of a spray-pipe taken on a line 33 of Fig. 2.

Fig. 4 is a cross section of the pipe taken. on a line 4- 1 of Fig. 3.

Referring now more particularly to the characters of reference on thedrawings, the numeral. 1 denotes the carbureter in general, providedwith the usual throttle valve 2 mounted on a stem 3, and with an airintake portion 4; communicating with the body 01 the carburetor by athroat 5.

Our improved water-feeddevice consists of a cylinder 6, closed at bothends, and secured to the engine or. the framev on which it is mounted bymeans of a clamp-bracket 7, the axis of the cylinder being preferably atright angles to the stem 3 of the carbureter and substantially in thevertical plane of the stem adjacentits outer end.

' The end of the cylinder nearest the carbureter is preferably formed asa removable cap ,8 with which is formed an arm 9 extending lengthwise ofthe cylinder and away therefrom, and preferably positioned in.

alinement with the outer cap.

Pivoted at the outer endof the arm 9 is a flat bar 10 extending acrossthe plane of the axis of the cylinder substantially at right anglesthereto, being adapted to bear against a cam member 11 removablyand-adjustably mounted on the throttle valve stem 3 by means 01 a setscrew 11.

Formed integrally with the cap 8 and. projecting outwardly therefrom isa concentric sleeve 12 in which is slidably mounted a taper-valve member13 whose stem 14 projects fromthe outer end of the sleeve and isarranged to press constantly against the bar 10 by reason of a spring 15about the stem, which spring also tends to hold periphery of the thevalve 13 closedto prevent communication from the cylinder 6 to a pipe 16which connects with the sleeve12 inwardly oi the valve therein andextends over the carbui-eter at the throat 5 and is seated in a slot 17out therethrough, the under side of said pipe being provided with a lineof small holes 16 communicating with the interior of said throat, theouter end of the pipe being closed.

The outer end of the sleeve 12 is provided with a packing gland and nutas at 18, to.

aim

the stem that when the valve 2 is closed the valve 13 1S likewiseclosed.

Then as the said throttle valve is opened,.

the air being}; drawn in through the intake 4 prior to the mingling ofthe two with the kerosene or other fuel.

It will he noted that the bar 10 is a lever, whose fulcrum at itspointo't connection with the arin 9, and hence the amount the steel ismoved by the movement of the earn depends on the position of the cam onthe stem 3, Thus by adjusting the position of said cam the amount ofopening of the valve 13 and hence the quantity of water or steai'nadmitted to the carhureter may be regulated. to suit differentconditions.

This condition may he obtained by any suitable means certain of whichwill be obvious. v

The device while adaptable for use'with any internal combustion engines,is especially suited foruse in connection with tractor engines which arecalled upon to work tor long periods at a stretch and under full insane?power, which not only tends to heat up the motor, but COHSLUIIQS a largequantity of fuel.

From the foregoing description it will be readily seen that we haveproduced such a device as substantially "fulfills the objects of theinvention as set forth herein.

While this specification sets forth in detail the present and preferredconstruction of. the device, still in practice such deviations from suchdetail may he resorted to and. do not form a departure from vthe spiritof the-invention, as defined by the appended claim. l

Having thus described our invention what we claim as new and useful anddesire to secure by Letters Patent is:

In combination with the air passage n1e1nher of a carbureter providedwith a trans verse slot on one side, a water supply pipe terminating ina portion seated in said slot, said portion being provided withaplurality of spray-holes along the face thereof projected into the slot,the end of the pipe being closed.

In testimony whereof we affix our signatures BURT C. ALVORD. CHARLES A.GILMER.
